CARRIAGE-BOW.

SPECIFICATION forming part of Letters Patent No. 403,091, dated May 14, 1889.

Application filed March 5, 1889. Serial No. 301,839. (No model.)

To all whom it may concern:

Be it known that I, JAMES C. 0088, a citizen of the United States, residing at Cleveland, in the county of Ouyahoga, State of Ohio, have invented certain new and useful Improvements in Carriage-Bows; and I do hereby declare the following to be a full, clear, and exact description of my invention, such as will enable others skilled in the art to which it relates to make and use the same.

My invention relates to improvements in tubular bow-sockets for buggy-tops.

The object of the invention is to strengthen such bow sockets, simplify their construction, and cheapen their manufacture.

My device is fully described herein, and shown in the accompanying drawings, and the matter constituting my invention is defined in the claims.

In the drawings, Figure 1 is a view of my improved bow-socket. Fig. 2 is a longitudinal sectional view of the same, and shows its combination with a broken section of the short bow. Fig. 3 shows details of the de vice, and Fig. 4 is a cross-section of Fig. 1 at m w.

The bows of buggy-tops are sometimes subject to considerable stress. Previous to my invention manufacturers sought to strengthen the bows when made of wood by slitting the wood and placing therein a tapering piece of sheet-steel, and when made of metal tubes they sought to strengthen the bows by filling the tubes with wood, and attempts have been made to further strengthen the wood-filled tube bows by inserting a tapering piece of sheet-steel in a slot cut in the wood filling. The difficulty with wood bows having a metal strip placed in a slit made in the wood is that the straining and twisting of the bow loosens the metal strip and weakens the bow throughout its length, and causes it to break where the steel strip ends. The constant straining and twisting of the tubular bows filled with wood and having a strengthening plate placed in a slot cut in the wood filling loosens the wood, allows the wood to turn in the tube, thus weakening them through their whole length, and they frequently break near the inner end of the slat-iron. Again, the expense of manufacturing the latter class of bows is increased by the necessity of milling the slat-iron or pin.

My device is provided with two metal tubes, one fitting snugly within the other. The outer tube, A, is made in the ordinary way, the seam a. being folded upon the inside of the tube. The inner tube, B, is not seamed, but is left with a narrow slit, 1), as shown in Fig. 3. The inner tube, B, is made of such. size that it is driven tightly into the outer tube, A, the edges of the slit 1) firmly gripping the folded seam a. The outer tube, A,- extends a little below the lower end of the inner tube, B, as shown at M. The top of the inner tube falls below the top of the tube A, as shown. The slat-iron O is provided with shoulders c and c and the shank c is driven into the tubes after the tube B is driven into the tube A. The slat-iron O and the tubes A and B are then welded together. The upper end of the inner tube, B, may be left open; but it is preferably closed by bending the metal over, as shown at B. The end of the short bow Dis fitted snugly inside the outer tube, A, its end resting against the upper end of the inner tube, B. v

My bow-socket possesses great strength and rigidity. It is very strong throughout its entire length, and especially at the shank 0, 8o where the bows are most liable to break. Their manufacture is cheaper than other tubular bows, as the wood filling is dispensed with, and the slat-iron C does not have to be milled.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. The within-described bow-socket, consisting of the tube A, the tube B fitted therein, 0 and the slat-iron O, substantially as shown.

2. The within-described bow-socket, consisting of two tubes, one tube being fitted within the other, and the slat-iron, substantially as shown.

3. In a bow-socket, the double tube, one tube being fitted within the other, substantially as shown.

4. In a bow-socket, the tube B, having the the tube A, the tube 13, fitted. within the tube slit 1), in combination with the tube A, substantially as shown.

5. The combination, in a carriage-bow, of 5 the tube A, the tube B, fitted within the tube A, and the short bow D, substantially as shown.

6. The COI11bi111-tiOl1,il1 a carriage-bow, of

A, the slat-iron C, and the short how 1), substantially as shown.
